The fragrance of the herbs filled the entire campsite. Although Zhao Hai had not started refining the herbs, there were already quite a lot of herbs in the campsite. These herbs were collected by the group. They had to be processed before they could be refined.
Meanwhile, Zhao Hai had started to make the tools for refining herbs. The best tool for refining herbs was a cauldron, but Zhao Hai couldn't make a cauldron for refining medicine, so he had to use something else.
However, ordinary metal pots and the like were not suitable for refining medicinal herbs because metal contained gold Qi, which was too sharp and overbearing. If this kind of gold Qi entered the medicine, the medicinal properties would change, which was not good. Therefore, people generally used clay pots or mud pots when decocting medicine. Very few people would use iron pots to decoct medicine.
